Abstract

A network of both existing and proposed flood control reservoirs in Iowa will make vast amounts of additional habitat available for fish populations. Approximately 30,000 surface acres of reservoirs will be operational within the near future. Much of this additional habitat is conducive to rough-fish species, but harvest of the resource is extremely low or absent. Low harvest usually results from disinterest of anglers for rough fish. The primary objectives were achieved by a systematic procedure outlined an integral part of the investigation. First, population estimates were made and biological statistics collected on age structure, growth, length-weight relationship, body condition, mortality rates and total catch for each type of gear.
